That Mars is inhabited by beings of some sort or other we may consider as certain as it is uncertain what these beings may be.

The whole object of science is to synthesize, and so simplify; and did we but know the uttermost of a subject we could make it singularly clear.

Ever since celestial mechanics in the skillful hands of Leverrier and Adams led to the world-amazed discovery of Neptune, a belief has existed begotten of that success that still other planets lay beyond, only waiting to be found.

There are celestial sights more dazzling, spectacles that inspire more awe, but to the thoughtful observer who is privileged to see them well, there is nothing in the sky so profoundly impressive as the canals of Mars. Fine lines and little gossamer filaments only, cobwebbing the face of the Martian disk, but threads to draw one's mind after them across the millions of miles of intervening void.

Irrigation, unscientifically conducted, would not give us such truly wonderful mathematical fitness [as we observe in the Martian canals]. . . . A mind of no mean order would seem to have presided over the system we see-a mind certainly of considerably more comprehensiveness than that which presides over the various department of our own public works.

Now when we think that each of these stars is probably the centre of a solar system grander than our own, we cannot seriously take ourselves to be the only minds in it all.

Bright points in the sky or a blow on the head will equally cause one to see stars.
